塔北地区下石炭统含盐层系的沉积演化及成盐机理

根据钻井、测井和地震资料，研究了塔里木盆地北部艾协克—桑塔木地区下石炭统含盐层系的沉积特征，恢复了早石炭世沉积岩相古地理环境，对含盐层系的垂向层序、地化特征、沉积环境和成盐机理作了初步探讨，建立了研究区下石炭统含盐层系的成盐模式。认为该区下石炭统的含盐层系不仅具有良好的储盖配置，而且由于盐体的塑性流动形成了一系列重要的含油气构造，具有良好的油气勘探远景

SEDIMENTARY EVOLUTION AND SALT FORMING MECHANISM IN LOWER CARBONIFEROUS SALT BEARING SERIES, NORTHERN TARIM BASIN

Based on drilling, well logging and seismic data, combining with sedimentary characteristics of Lower Carboniferous saltbearing series in Aixieke-Sangtamu of northern Tarim basin, lithofacies and paleogeography in Early Carboniferous were resumed, vertical sequence, geochemical characteristics, sedimentary environment and saltforming mechanism of saltbearing series were preliminary discussed, saltforming model of Lower Carboniferous saltbearing series in study area was established. It is considered that Lower Carboniferous saltbearing series has better reservoircaprock assemblage and exploration prospects because of a series of hydrocarbonbearing sturcture as a result of plastic flowing of salt body.
